MILK-BOTTLE CONSTRUCTION.

Refile for abandoned application Serial No. 592,183, filed October 4., 1922.

December 17, 1925.

In carrying out the present invention it is my purpose to provide a milk bottle which will be formed of aluminum, thereby minimizing breakage of the bottles in the handling thereof by the cleansing and filling machinery.

It is also my purpose to provide an aluminum milk bottle wherein the cap receiving groove at the upper end of the neck of the bottle will be formed in such manner as to effectively hold the cap in the cap receiving groove or rabbet, so as to prevent casual or accidental displacement of the cap and also eliminate the passage of dust, dirt and other foreign matter to the interior of the bottle.

With the above recited objects in view, and others of a similar nature, the invention resides in the construction, combination and arrangement of parts set forth in and falling within the scope of the appended claim.

In the accompanying drawing:

Figure 1 is a fragmentary side elevation partly in section of a milk bottle constructed in accordance with my invention.

Figure 2 is a fragmentary vertical sectional view through the neck of the bottle showing a modified construction.

Figure 3 is a top plan View of the construction shown in Figure 2.

Referring now to the drawings in detail, and particularly to the form of my invention shown in Figure 1, 1 designates a bottle which, in accordance with my invention, is formed of aluminum so that the bottle may be handled by the cleansing and filling machinery without breakage.

2 designates the neck of the bottle, the upper open end of which is formed with the usual annular head 3. The neck 2 of the bottle on the inner wall of the bead 3 is undercut, as at 4, in accordance with my invention, so as to receive the marginal edge of a cap 5. Owing to the fact that the neck of the bottle is undercut, as at 1-, instead of a vertical cut, as is usual, the cap 5, when passing the outer end of the undercut 4:, has a tendency to compress, and when the lower end of the undercut portion is reached the cap expands, thereby securely locking the cap in the neck of the bottle. At the bottom of the undercut 4 is a shoulder 6 against which the cap rests, the shoulder This app1ication filed Serial No. 76,129.

6 and the bottom end of the wall of the undercut cooperating to maintain the cap in position.

In the modified construction shown in Figures 2 and 3 of the drawings, the inner surface of the bead 3 on the neck 2 of the bottle is formed with a straight rabbet 7 having the usual vertical wall, instead of the undercut wall, as shown in Figure 1. In this instance the vertical wall of the rabbeted portion is formed with inwardly extending lugs 8 spaced apart equal distances around the mouth of the bottle and having their inner edges rounded, as at 9, in a vertical direction, so that as the bottle cap 5 passes the center of the curved edges 9 of the lug 8, such cap will be compressed and will then expand when leaving the lower edges of the lugs. The shoulder 10 at the bottom of the rabbet 7 is spaced apart from the lower ends of the lugs 9, as clearly illustrated in Figure 2 of the drawings, so that after the cap has been forced by the lugs and relieved of the influence thereof, it may expand into the seat provided by the shoulder 10 and the vertical wall of the rabbet 7.

From the foregoing description, taken in connection with the accompanying drawings, it will be seen that by reason of my improved milk bottle being made of aluminum, breakage of the bottle in the handling thereof and in the washing and filling operations will be eliminated, while at the same time the bottle will be rendered sanitary. Furthermore, owing to the formation of the groove in the mouth of the bottle the cap will spring into place when the shoulder of the rabbeted portion is engaged by such cap, thereby securely holding the cap across the mouth of the bottle and preventing the entrance of foreign matter to the contents of the bottle.

I have entered into a detailed description of the construction and relative arrangement of parts embraced in the present and preferred embodiments of my invention with a view to imparting a full, clear and exact understanding of the said embodiments. I do not desire, however, to be understood as confining myself to the said specific construction and relative arrangement of parts, inasmuch as in the future practice of my invention such changes or modifications may be made as fairly fall within the scope of my invention as defined by my appended claim.

Having thus described the invention, What 5 is claimed as new is:

As a ne article of manufacture, a niilk bottle comprising a neck having the month thereof rabheted a plurality of spaced upright lugs with vertically rounded inner edges on the inner upright surface of the month, an annular shoulder formed in the mouth of the bottle and separated from the lower ends of the lugs by an intervenine space and adapted to seat a mill: bottle ("up (llSPOSQLl between it and the lower ends of the h s the cap upon riding); ever the lugs heing; eoinp ess'ed and being, therefore. adapted to extend between the lugs at the lower ends thereof and the shoulder; whereby the cup is locked by the lugs in place.

In testimony whereof I afhx my signature.

JOHN JAMES MARSTELLAR.
